Apparently, I am somewhat of a masochist. Haa! Had I not purchased all the parts already, I would have likely changed my plans on this build.
Update:
I've taken measurements (multiple times) and although I still don't trust the numbers, the diagnal-section and cross section measurements are within ~1/16 of an inch. I would like to validate my findings but I cannot find these measurements in my books. can someone provide me with these three measurements:
Center of door striker to door striker; Inner rocker to inner rocker at the kick panel; and Inner rocker to inner rocker at the front leaf spring / frame rail area.
I can build up my bracing once I have some affirmation that my measurements are good.
